A wireless stethoscope with noise reduction function

Abstract

The invention discloses a wireless stethoscope with a noise reduction function, which comprises a stethoscope head body, a noise reduction sponge cover plate, a protective frame, a second sound pickup, a filter amplifier and a Bluetooth module. The bottom end of the stethoscope head body is screwed with an aluminum Diaphragm, the connecting plate is provided with a chute, the bottom end of the slider is movably connected with a support rod, and the bottom end of the support rod is interactively connected with a noise reduction sponge cover plate, and the sound insulation frame is rotatably connected with The shaft is fixed, and a turntable is welded and fixed on the fixed shaft, and a transmission belt is meshed and connected to the turntable. The wireless stethoscope with noise reduction function is provided with a rubber pad, which can effectively increase the friction force of the pick-up, thereby effectively increasing the stability of the staff's pick-up, and at the same time, the disinfectant stored in the storage tube can pass through the through hole on the rubber pad Infiltration or spraying can effectively disinfect the hands of the staff in a timely and effective manner, thereby effectively preventing the spread of the virus.

Description

technical field [0001] The invention relates to the technical field of electronic stethoscopes, in particular to a wireless stethoscope with noise reduction function. Background technique [0002] Auscultation is the basic method for doctors to diagnose patients' symptoms, and stethoscope is the most commonly used diagnostic tool for doctors. Although the traditional The close-range auscultation method virtually increases the risk of infection for doctors, so wireless stethoscopes are now widely used, which is a good solution to the problem of increasing the risk of infection by close-range auscultation. [0003] Now most wireless stethoscopes with noise reduction function have the following problems: [0004] 1. The auscultation probe of the wireless stethoscope is equivalent to a sound collection device, and does not distinguish useful signals from ambient noise, so they will be collected together, when in harsh external environments, such as noisy accident scenes and bus...
